摘要
对鹤壁煤矿区第10矿煤矸石进行连续淋溶试验,模拟煤矸石矿井填充后对地下水环境的影响。测定pH值、电导率、F-、总硬度、Zn、Mn、Cr6+、Cd、Cu和Pb等项目,实验结果表明,煤矸石淋出液中F-和Cr6+超标,Mn接近标准,pH值偏高,对地下水环境存在一定影响。其他各元素含量甚微,多未检出。
Based on No. 10 mine of the Hebi Coal Company Group, the influence on groundwater after filling-in undergound with gangues was simulated through the continuous simulative sprinkling experiments. Index tested in the experiments were pH, conductivity, F^- , total hardness, Zn, Mn, Cr^6＋ , Cd, Cu and Pb. The experiments show that in the eluviation water, the values of F^- and Cr^6＋ exceed the standards, and Mn approaches the standards, and pH is too high, and may pollute undergroud water. While the contents of other heavy metals are very little and cann＇t be detected.
